CLOD-PULVERIZER.

To all whom it may concern:

Be lt known that I, JOSEPH F. WITTLER, a

useful Improvements in Clod-Pulverizers, ofwhich the following is a specification, reference being had to the accompanying drawl s' This invention has relation to clod pulverizers and has for its object to'provide a machine of simple structure adapted to be drawn over the soil, thesaid machinecarrying a disk gang journaled for rotation and which is adapted to engage the clods and pulverize the same. With the above object in view the machine includes a crankor arch axle which is supported upon ground wheels. A primary frame is mounted upon the intermediate portion of the axle and a .draft tongue is connected with the, said primary frame. .A secondary frame is carried below the primary frame and is con-' nected to the same byuprights, the said secondary frame' is also connected with the axle whereby rigidity is imparted to the entire structure. A shaft is located below the secondary frame and disks are mounted The shaft is loosely ondary frame and means is mounted upon the primary frame for raising and lowering the shaft. Fenders are pivotally-connected with the secondary frame and lie between the rear portions of the disk, the springs are connected at theirupperends with the intermediate portions of the axle and at their lower ends are connected with the fenders and are are under tension with the tendency to hold the lower portions of the fenders against collars which are located between the disks and which serve to hold the disk in spaced relation.

. With these andother objects in view,' the invention consists in certain novel features ofconstruction as hereinafter shown and described, and then particularly pointed out in the claims and in the drawings illustra- .tive of the preferred embodiment of the invention.

In the acolnpanying drawings: Figure 1 is a side elevation of the clod pulverizer with parts broken away. 'Fig. 2 is a vertical'sectional view of the same cut on the line 2-2 of Fig. 3. Fig. 3 isarear elevation of the clod pulverizer.

Corresponding and like parts are referred to in the following descriptionand indicated mall the views of the accompanying draw ings by the same reference characters.

' .The clod pulverizer includes an axle 10 which is provided with downwardly disposed cranks 111. The cranks 11 are, ap-

proximately parallel whereby an axle of U- f shaped configuration is provided and the said cranks merge into. an outwardly, disposed spindle 12. Ground wheels 13 are journaled upon the spindles 12 and serve as supports for the axle and the parts mounted thereon. A' primaryrectangular. frame 1% is located under the intermediate portion of. the'axle lO and includes end bars 15. The end bars 15 are connectedwith the axle 10 by means of U -shape'd clips 15 as clearly shown in;Figs,;z1=and 3; lBracesqlfi are mounted atZthe forward portion of the frame l-t and are provided with forwardly disposed ends 17. .g The rear end of the tongue 18;i's secured to the end portions 17.

ofthe braces 16 by means of bolts 19. A double tree 20 is connected tothe tongue 18 by means of abolt 21 and swingle trees 22 l are carried bythe double tree 20in the usual manner: A secondary rectangular frame similar to said primary frame is located below and parallel to the primary frame 14cv I and the said secondary frame consists of a rear bar 23, and a forward bar 24:, the ends of which are bent intoend sections 25 and 26 respectively. Said end sections 25 and 26 are secured to the portions 11 of the axle 10 by means of bolts 27. Uprights 28 connectthelrear part of the frame 14: with the 7 rear bar23 of the supplemental frame and 2' l uprights 29 connect theforward bar 2 of the "supplemental frame with the braces 16 at their forward edgesflandextend below said secondary frame. Securing bolts 30 are employed for attaching the uprights 28. and 29 to the parts as above stated. Braces 31 extenddown from the forward part of the frame 14 to the end sections 26 of the forward bar'24: of the secondary frame. The

uprights 29 areprovided. at their lower ends with openings 32 which, receive loops 33 carriedat the forward end'sof rearwardly extending rods 34. Bearings 35 are carried at the :rear portions of the rods;34 and the l shaft 35is journaled in the bearings 35. The bearings 85 are connected with the rods 34 by means of bolts 36. The rear ends of the rods 34 are pivotally connected by means of pins 37 with the lower ends of links 38. Bolts pivotally connect the upper ends of the links 38 with the rear ends of adjusting levers 40. The levers 40 are fulcrumed upon pivots 41 which in turn are carried by segments and mounted upon the intermediate portion of the axle 10. The segments 42 are provided at their upper edges with teeth 43. Pawls 44 are carried by the levers 40 and are operatively connectedin any appropriate manner with handle grips 45 which are pivoted at the free end portions of the levers 40. The pawls 44 are adapted to engage between the teeth 43 of the segments 42 whereby the levers may be held at adjusted positions.

A bar 46 is located under the secondary frame and is pivotally connected with the rear bar 23 of the said frame by means of loops or links 47. Fenders 48 are attached to the bar. Circular disks 36' are mounted upon the shaft 35 and are held in spaced relation by means of collars 37' which are loosely mounted upon said shaft 35'. The

lower end portions of the fenders 48 lie be tween the disks 36. The fenders 48 are connected with the bar46 by means of bolts 49.

Springs 50 are connected at their upper ends with an intermediate portion of the axle 10 and at their lower ends are connected with the fenders 48. The said springs 50 are under tension so that they will always hold the free end portions of the fenders 48 against the peripheries of the collars 37 when the shaft 85' is in its lowermost or Iuppermost positions or at'any point between the said positions. A seat is mounted upon said posts 52 which in turn are mounted upon the primary frame 14. bracing seat post 53 extends from the seat 51 to the intermediate portions of the axle 10. The upper or free ends of the levers 40 are located within convenient reach of one occupying the seat 51.

From the above description, it will be seen that as the machine is drawn over the soil the levers 40 may be moved so that through the links 38 the rear portions of the rods 34 may be raised or lowered. Therefore the disks 36 may be positioned to operate at any desired depth below the surface of the soil. As the machine moves in a forward direction the disk 36 rotates and as they encounter the clods they pulverize the same. Should any of the soil adhere to the sides of the disks or should any of the clods wedge between the disks, this material will be carried in an upward direction and when it encounters the fenders 48 the said fenders will force this material from between the disks. Therefore the disks will not accumulate material and the space between the same will at all times be kept open and free. When it is desired to transport the machine from onepoint to another without having the disks 36 in contact with the ground or soil, the levers 40 may be moved so that the rear ends of the rods 43 will be elevated. Thus the. disks 36 will be moved above the surface of the soil. At the same time the springs 50 will contract and draw the lower ends of the fenders 48 in an upward direction. The upward movement to the lower portions of the fenders 48 is at all times limited by the positions of the collars 37' which are located between the disks 36. Therefore it will be seen that a machine of simple structure is provided which may be efficiently used for pulverizing and preparing the soil for planting and other purposes. It will also be seen that means is provided for keeping the disks free from accumulations and that the said freeing means adjust themselves automatically so as to assume predetermined relations with respect to the disks irrespective of the vertical positions of the disks.
